About this item

  • HSS Titanium Coating: Our high-speed steel drill bits, fortified with a titanium coating that makes the drill bit harder than a typical HSS bit, can reduce the friction drill, and perform well in heat, corrosion, and rust resistance.
  • Precision-Engineered Design: Two-flute spiral grooved design deburrs chips, dust and debris for clearance and smooth cutting. The 118° split point tip drill reduces friction, pressure, and heat, making the drill bits long-lasting and efficient.
  • Wide Application: Our step drill bit can process different diameter holes, and can be used on materials such as metal heavy-duty, iron, aluminum, brass, plastic, aluminum alloy, wood, plastic, etc. Suitable for home DIY and general use.
  • Quick Change: The 1/4-inch hex shank fits easily and securely into all power tools to prevent slippage and shedding during rotation.
  • 31 Step Sizes: 13 step drill (1/8, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 13/32, 7/16, 15/32, 1/2-inch) 6 step drill (3/16, 1/4, 5/16, 3/8, 7/16, 1/2-inch) and 12 step drill (3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8-inch)

Durable and functional for almost any DIY application they are great step bits and good value for the money. Easy to use just drill straight down and you won't get no wobble. I'm using them to drill holes in mason jar lids to make mycology liquid culture jars.

These aren't super heavy duty but for the price you can't go wrong. Seller refunded me well out of the return window after the largest one of these broke. I tried reordering and Amazon lost the shipment. A+ to the seller and their customer service. The bits themselves seem to work pretty well if your not too hard on them. I used them for some copper buss bars and some aluminum Diamond plate and they seemed to go through the thinner metals pretty fast. Overall I'm happy with them for the price and would purchase again.

I’ve used these to drill out some holes on a thicker plastic piece and they worked great. Feels durable and are great tools to have if you like DIYing stuff.
